Definitions
- the present invention relates to a knee prosthesis, called posterior stabilized.
- the prosthesis has a femoral part intended to be fixed at the distal end of a femur, in particular by anchoring, and a tibial part, intended to be fixed to the proximal part of a tibia, in particular also by anchorage.
- an insert is provided (also called meniscus), usually in a softer material than that of the parts femoral and tibial, such as polyethylene.
- the insert On its upper part, the insert has generally concave surfaces on which they come into contact sliding or rolling two condyles from the femoral part.
- a stud says tibial stud, in particular protrudes perpendicular to the base of the insert ,. Between the two condyles of the femoral part, an opening is formed, called the inter-condyle space, into which the tibial stud enters. To delimit this opening, on the side posterior, a so-called femoral stud is provided, extending transversely to the stud tibial, from one condyle to another.
- the femoral stud In general from a bending angle of about 30 °, comes into contact with the stud tibial. In current prostheses, beyond 90 ° of flexion, the femoral part presents a high risk of backward recoil, which can result in efforts important and eventually a dislocation of the prosthesis.
- the present invention aims to overcome these drawbacks of the prior art by proposing a knee prosthesis, called postero-stabilized, more safe and in particular whose risk of dislocation is reduced, in particular for large flexions, beyond 90 °.
- the knee prosthesis is as defined in claim 1.
- the femoral stud tending to "stick" to more and more to the tibial insert and therefore to have less and less tendency to "unhook” from the tibial stud from above.
- the present invention also relates to an insert such as defined in claim 10.
- the femoral stud for example of shape cylindro-circular, rolls or slides on the posterior surface of the tibial stud, as and as the knee flexes.
- the point of femoral-tibial-stud contact tends to go up (i.e. away from the base of insert) as the knee flexes.
- the curve of contact has a line segment, in particular in its part intermediate between the base and the top.
- the curve at least in part, is such that from a given point to the top, a point in the curve is all the more posterior that it is close to the top.
- the present invention also relates to a knee prosthesis having an insert according to the invention.
- the femoral part of a so-called tibial prosthesis postero-stabilized comprising two condyles between which a stud extends femoral cylindrical to define an opening to be penetrated by the tibial stud of the tibial insert, the tibial insert having upper surfaces concaves in contact with the convex outer surfaces of the condyles, the contact being defined by a contact area having a central point, is such that the curve defining the cross-section of the femoral stud is defined by so that the central point of the contact zone undergoes translation in the posterior direction, which decreases according to the angle of flexion until becoming zero for a bending angle of 80 to 90 ° and remains zero until a bending maximum of 120-130 °.
- the curve delimiting the cross-section has at least two segments of convex shape, joining at a point called vertex, the point resulting from the projection perpendicular to the vertex on a line segment connecting the two segments convex being closer to the posterior end of the line segment, than of the anterior end, in particular according to a ratio of 1/3 to 1/6.
- the convex shape segments of the curve defining the cross section transverse of the femoral stud correspond substantially to segments of the curve defined by the cross section in the anteroposterior or sagittal plane from the outer surface of the condyles, except for homothety.
- FIG. 1 it is represented in the anteroposterior plane or sagittal, i.e. the plane defined by the longitudinal axes of the femur and tibia, when the knee is bent, a tibial insert 1 in polyethylene, comprising a stud tibial 2 projecting in the vertical direction from a base of the insert, the base having two upper contact surfaces 3 with which the outer surfaces condyles 4 are in contact.
- a space is formed intercondylar crossed by the tibial stud 2.
- a femoral stud 5 extends from a condyle to the other in the medio-lateral direction (perpendicular to the plane of the figures). In extended position of the knee, the tibial stud and the femoral stud are at a distance one of the other.
- the femoral stud comes into contact on a posterior face 6 of the tibial stud.
- Each condyle is in contact with the insert following a contact zone, having a central point 8.
- the cross section of the femoral stud is chosen, taking into account the shape of the condyles, the contact surfaces of the insert and the face posterior of the tibial stud, so that point 8 is fixed for any angle of flexion between 80 to 90 ° and 130 °.
- the section transverse of the femoral stud consists of a straight segment 10 having a posterior end 11 and anterior end 16 from which extend two segments of curves 12 and 13, posterior and anterior. Both segments of curves are convex and in particular here they are arcs of a circle. They meet at a vertex 14.
- the perpendicular projection 15 of the vertex 14 on the right 10 is closer to the posterior end 11 than the anterior end 16. In particular, the ratio of the distance from 15 to 11 over the distance from 15 to 16 is between 1/3 and 1/6.
- the shape of the closed curve 10-12-13 corresponds, except for homothety, to the shape of the outer surface 21 of the condyles below the horizontal in position knee extension supplemented by a horizontal segment 20 (partly in dotted in the figure).
- the tibial stud has at its top a sort of beak 22 protruding in the posterior direction.
- the posterior face 6 of the femoral stud has the shape of a bowl whose bottom 25 is substantially flat and extends over substantially the entire vertical extent of the stud.
- the rear face 6 defines a contact curve.
- Point 22 summit is more posterior than all of the points of the tibial stud from the start of line segment 25 to vertex 22.
- the points of the curve are all the more posterior they are close to the top 22.
- the line segment 25 between the base and the vertex 22 is perpendicular to the base of the tibial insert, especially on the underside of the insert which rests on the tibial plateau.
